He made the remarks after senior Congress leader PL Punia said that he was witness of a meeting between Mallya and Jaitley in Parliament during 2016 Budget session. He claimed that the meeting appeared to have been of a formal nature and lasted 15-20 minutes.

Jaitley had denied meeting the embattled liquor baron after the latter said that he had met the senior BJP leader before leaving India in 2014.

Refuting the charges made by Mallya as "factually false," Jaitley claimed, ''The statement is factually false in as much as it does not reflect the truth. Since 2014, I've never given him any appointment to meet me and the question of his having met me does not arise.''

FM Jaitley also accused Mallya of ''misusing'' his stature as the Rajya Sabha MP. ''Vijay Mallya "misused" privilege of being Rajya Sabha MP to catch me in the corridors of Parliament on one occasion while he was walking out of the House to go to his room, '' the Finance Minister said.

He said Mallya, while walking alongside, "uttered a sentence that 'I am making an offer of settlement'. Having been fully aware of his 'bluff offers', without allowing him to proceed with the conversation, I curtly told him 'there was no point in talking to me and he must make offers to the bankers.'"

"I did not even receive the papers he was holding in his hand," Jaitley claimed.

The 62-year-old former Kingfisher Airline boss said he met the Finance Minister before he left. "I repeated my offer to settle with the banks. That is the truth," he had said without naming the minister.
